spring中使用hibernate

public void delete (int[] deleteKey) {
        StringBuffer hql = new StringBuffer("delete Employee where employeeKey in (");
        for (int i = 0; i < deleteKey.length; i++) {
            if (i == 0) {
                hql.append(deleteKey[i]);
            } else {
                hql.append(", ");
                hql.append(deleteKey[i]);
            }
        }
        
        hql.append(")");
        final String hhql = hql.toString();
        
        HibernateCallback action = new HibernateCallback() {
            @Override
            public Object doInHibernate(Session session)
                    throws HibernateException, SQLException {
                Query q = session.createQuery(hhql);
                q.executeUpdate();
                return null;
            }
        };
        
        this.getHibernateTemplate().execute(action);
    }
